Modules to be placed directly upon heavy duty (HDPE, Polypropylene, TPO, EPDM or recyclable PVC) slip sheet/root barrier of 40-60 mil. thickness with effectively bonded seams. This is placed as an additional protective barrier above roof waterproofing membrane and extended 3 inches vertically along parapet to ward against edge abrasion. This may also be glued to parapet if manufacturer approves.Confirm suitability of waterproofing membrane with manufacturer. Alternatively low profile drain boards work well and manufacturers of cold fluid applied reinforced urethane membranes typically warrant their systems for use in conjunction with the LiveRoof® system.

IRRIGATION SYSTEM

Irrigation is recommended for backup during prolonged hot, dry and windy weather patterns.Simple overhead system is inexpensive and effective insurance. Irrigation requirements are dependent on plant selection, climate and roof design.

In hot, humid or arid climates, irrigation systems should always be installed and used as needed given weather conditions.
Similarly, irrigation systems are necessary on pitched green roofs and those in wind-challenged conditions, such as in coastal areas and on tall buildings.

If LiveRoof Lite system is used, irrigation will be essential in all climates.
If the Deep system is used and populated with non-succulents, irrigation is also essential.

EDGE TREATMENTS

Coengineered RoofEdge® aluminum edging with adequate drain perforations recommended. Any edging should allow for adequate drainage (extending to the bottom of the edging) with sidewalls tall enough to completely cover the modules and contain the soil.
